No heartbeat 7 weeks but hcg rising

Was just wondering if anyone has had a similiar situation and the outcome be ok ? I know it’s very common to not detect a heart beat before 8 weeks but my crl is measuring 8.5mm and in the last two days my hcg has gone from 129000-169000. I have to wait one more week for another ultrasound but they did tell me expect a misscarriage as my crl is over 7mm and the levels being high. Should they start dropping ?

This does happen!  You are early and sometimes they can't see the heartbeat. Do they see the sac?  I have to ask this, have they made sure you aren't having an ectopic pregnancy (which can be the result in high HCG numbers)? Yes, if you are miscarrying, your hcg numbers should drop.  Let us know what happens and sorry for what you are going through.  hugs

These are the criteria radiologists use to determine if findings on obstetrical ultrasound are diagnostic of miscarriage vs. suspicious for but not diagnostic of miscarriage: https://www.acog.org/-/media/Practice-Bulletins/Images/pb200a.ashx. Embryo with crown-rump length of 7 mm or greater and no heartbeat is diagnostic of miscarriage. It used to be embryo with crown-rump length of 5 mm or greater and no heartbeat, but the guidelines were revised to be absolutely sure that the pregnancy is not viable. Sorry for your loss :(
